Frequently Asked Questions
Does this manual cover the notorious AJ-V8 coolant elbow failure?
Yes. The X308 AJ-V8 is well known for cracking plastic coolant elbows and crossover pipes that can cause sudden coolant loss. The manual includes complete cooling system disassembly procedures, replacement part specifications, and torque values so you can address this issue correctly before it leads to overheating damage.
Does this cover both the standard XJ8 and the supercharged XJR?
Both variants are fully documented. XJR-specific content includes the Eaton M112 supercharger service procedures, the W5A580 transmission (used exclusively on supercharged models), the sport-tuned suspension setup, and the uprated Brembo-style braking system fitted to XJR models from 1998–2003.
Are wiring diagrams included for the air suspension system?
Yes. Electrical schematics cover the Computer Active Technology Suspension (CATS) system, including the compressor relay circuits, height sensor wiring, and the electronic control module. Fault-finding flowcharts help pinpoint common failures such as compressor burnout and ride-height sensor drift.
